Description
2 ]. A/ s; m3 e) @) \, f5 YThe ZCC1001E is a high voltage, non-synchronous
step-down converter operates over a wide range
input voltage 9V to 100V. The ZCC1001E
integrates a 120-V 400-mΩ high-side MOSFET.
5 Y! N) R& Q+ I) s# X& QThe ZCC1001E delivers 1A continuous load

operates with fixed frequency peak current control
with built-in compensation eliminates the need for
external components.
